Abstract

The stratigraphic sequence in the Beyköyü-GökçeyazÎ area, central Turkey, starts with the Palaeocene–lower Eocene Güneydağı Formation, including limestone interbedded with calcirudite, calcarenite, and marl. An angular unconformity separates the unit from the overlying Beyköyü Formation, which has two members: Kabaktepe gypsum and Kayalıdağtepe stromatolitic limestone. A Miocene lacustrine environment is inferred for the deposition of the Beyköyü Formation, based on the existence of blue-green algae (Schizothrix sp., Scytonema sp., and Phormidium sp.) as well as green algae (Chara sp.), lacustrine Gastropoda (Planorbarius sp.), and lacustrine ostracodes. The sequence continues with the upper Pliocene–Holocene Kuskuncuk Formation, containing alternations of conglomerate, sandstone, and mudstone, with caliche bands in some levels, which were deposited in alluvial fan and braided stream environments. Quaternary alluvium is the youngest unit in the sequence.
